Market context

BetBoom Team and Team Spirit face off in a best-of-one group stage match at the BLAST Slam, a Dota 2 tournament series that has drawn top-tier squads from the CIS and international regions. The match is scheduled for 26 May at 1:20 PM ET, with settlement contingent on a decisive result by 2 June.

The 100% implied probability reflects Team Spirit's standing as one of the strongest Dota 2 rosters in the world. Spirit won The International 2021 and have remained consistent top-four finishers at major events, whilst BetBoom—a CIS-based squad—typically competes in regional qualifiers and secondary-tier tournaments. Historical matchups between established tier-one teams and regional challengers in group-stage formats show the favourite rarely faces meaningful upset risk in single-elimination play, particularly when the skill gap is pronounced. However, a best-of-one format introduces inherent volatility; any team can win a single game through draft advantage, early execution, or tactical surprise.

Traders should monitor team roster confirmations and recent scrim results in the days before the match, as last-minute substitutions or injury announcements could shift the baseline. BLAST Slam's official schedule and broadcast timings should be verified against the settlement window, given that delays beyond seven days without completion trigger a 50-50 resolution. Recent Dota 2 tournament coverage from esports news outlets like Liquipedia and BLAST's own announcements will confirm whether either squad has withdrawn or faced logistical disruptions. The current probability leaves minimal room for contrarian positioning unless new information emerges about team preparation or roster changes.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Who Will Win, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

Is this market available outside the US?

Who Will Win is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
